APPARATUS FOR MAKING MORTAR.

SPECIFICATION forming part of Letters Patent No. 521,507, dated June 19, 1894.

Application filed May 18, 1893. Serial No. 474,697. (No model.)

To all whom it may concern:

Be it known that I, THOMAS D. MCCLARY, a citizen of the United States, residing in the city of Washington, District of Columbia, have invented certain new and useful Improvements in Apparatus for Making Mortar; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to mortar making apparatus, the object of which is to provide a complete apparatus or set of machines for handling, proportioning and mixing the ingredients of mortar and thereby economically obtain a constant quality and a superior product.

The invention consists in certain combinations of machines and instrumentalities hereinafter described and claimed. I

In my new organization and apparatus, many old devices and machines for performing different steps in the complete process of making mortar may be used, and I therefore do not limit myself in the general combinations to the special construction of any one of the parts embraced in said combinations, as any conventional means for performing the functions of the several machines or instruments are for the purposes of this application the equivalents of other instruments or machines which will accomplish the same result.

In the drawings, Figure 1 is an elevation of a suitable structure and of instrumentalities arranged within and upon the same, illustrating my invention. Fig. 2 is a sectional elevation of the same, on the line oc-0c of Fig. 1. Fig. 3 is a horizontal section, taken on the line' z z of Fig. 1. Fig. 4 is also a horizontal section taken on the line 1-=1 of Fig. 1. Fig. 5 is an enlarged sectional view of a hair-picker. Fig. 6 is an enlarged sectional view of a water meter adapted for my purposes. Fig. 7 is an enlarged sectional view of an adjustable lime meter and slaker. Fig. 8 is a top or plan view of the slaker. Fig. 9 is a horizontal section on the line 2-2 of Fig. 4, showing the gate or cut-off of the mortar mixer, and Fig. 10 is a sectional view of the sand meter, feed-regulator and screens.

The structure or support of the apparatus is,by preference, provided with five floors. On the top floor is supported a water tank W for supplying water under a head for distribution. Obviously, any other source of supply is the equivalent of this tank. The fourth floor supports sand bins or hoppers S and lime bins or hoppers L, and beneath this floor are suspended sandmeters s, water-meters w andlime meters Z. Lime slakers L L and hair-picker H are supported on the third floor and the mortar mixers M and the conveyor 0 for discharging the mortar are located on the second floor. The sand-meter sis located below the sand bins and discharges on to shaking screen A, and thence over chute B to mixer M. The lime meterl is also located below the lime bin and discharges to slaker L. A lime crusher X is located at a suitable point to discharge the crushed lime into an elevator well convenient for elevation to the hopper above.

E is an elevator for hoisting sand from a well located, by preference, below the first floor, to bins or hoppers S on the fourth floor and E is the lime elevator for a similar purpose. The lime-crusher comprises any suitable means for reducing the lime to about the size of nut coal. A device similar to a coal breaker is contemplated.

The water-meter, Fig. 6, consists of a vessel w provided with a graduated standard 6 and a float valve '0 adj ustably connected with said standard and is thus rendered adjust able. The water passes from meter through pipe 7 and cook 8 to slaker L The lime meter, Fig. 7, consists of a cylindrical chamber Z provided with a diaphragm 9 dividing it into equal compartments. Said meter is also provided with openings a a on .opposite sides of the cylinder. Each chamber is also providedwith a movable partition or false bottom 4 shown in dotted lines and with cleats 5-5 and set screws a for supporting and securing the partition at any point desired to alter the capacity to correspond with the character of lime and sand to be used, as sand and lime vary in such way that the relative proportions of the two have to be varied to produce a given quality. of mortar. The proportions also have to be varied in order to provide mortar of different qualities from given materials. Lime is discharged from bin or hopper to fill one compartment of the meter, which is then partially rotated by crank 23 so as to discharge its contents over chute b to slaker L, after which it is set in the position shown in Fig. 7 to receive another charge of lime.

The lime-slaker, Figs. 7 and 8, consists of a closed upright cylindrical tub or tank L provided with an annular channel or depression (Z and with a main port and screen or separator h in the bottom of the tank and with a second port and screen t' in the channel, both ports discharging into chute K leading to mixer M. There is also a gate or cutoff m in the channel discharging to spout n which leads to waste.

\Vithin the slaking tank are stirring blades or agitators oadapted to be rotated, as shown. III-OPGIatlOU, the blades agitate and mix the lime and water and as the lime becomes slaked, the lime paste passes through the screens to the mixer. The hard lumps of lime, stone and other refuse which will not pass the screens, accumulate in the channel and are periodically discharged through the gate 771. Beneath the screen-covered ports is a single perforated sliding gate 27 for simultaneously opening and closing said ports. The gate is operated by rack and pinion through lever 28 carrying a pawl for rotating the pinion shaft by means of a ratchet pinion, as shown in Figs. 1 and 7. The closed slaker has an inlet port to which a charging chute 1) leads, the chute or port being closed, during the process of slaking, by a suitable gate. I have shown, Fig. 7, the lime meter so made and arranged that it registers with the mouth of the chute and after said meter has discharged its contents to slaker it is moved far enough to close the passage between meter and slaker.

The mixer consists of a tank M having its bottom curved in the arc of a circle and provided with an interior swinging gate or cutoff G for closing and opening the port X of the tank to discharge the contents to 0011- veyer trough I whence the completed mortar is discharged to air-tight mortar vats K. The gate G is mounted on a pivot, as shown, and is conveniently operated from the third floor through lever N, link r and arm a. As shown in Fig. 4, the discharge port 0: extends only part of the length of the tank, it being understood that the blades 14 will operate as a conveyer to force the contents toward the port. Obviously, the gate may extend the entire length of the tank, if desired. The blades are rotated so as to force the contents toward the port at one side of the bottom of the tank.

The sand-meter, Fig. 10, consists of a cylindrical horizontal vessel 3 having two equal compartments 10--1O and having a mouth leading to and from each of these compartments. Sand from bin S fills one chamber of the meter and upon turning the vessel about one-half a revolution, the sand is discharged from one chamber and the other is brought to position and filled. A chute or trough T leads from sand meter to screen A, which discharges the screened sand to chute B and thence to mixer M. At the mouth of trough T is a feed-regulator V consisting of a rotating shaft having outwardly projecting blades for regulating the flow of sand from the meter to the screen, and forcibly discharging and scattering the sand on the screen, in a manner somewhat similar to that practiced by hand. The screen consists of a succession of sitters arranged and supported in any suitable way, as by brackets.

The hair-picker 11, Fig. 5, consists of a retary cylinder armed with teeth, a toothed concave and a hopper. This picker is arranged above the mixer and is designed to discharge directly into said mixer. A proper quantity of hair or fiber for a charge of lime and sand is put into the hopper where its bunches are broken up and the fiber separated, and introduced to the mixer in proper condition to be incorporated with the mortar. The vats K are made air-tight, so that the finished mortar may be kept for an indefinite period without deterioration, which takes place in the open air when the hydrate or lime paste ab- 1sorbs carbonic acid and becomes carbonate of I have shown many of the parts in duplicate to provide a continuous apparatus, but it is evident that a single set will operate on the same principle as the duplex arrangement shown. I have also shown shafting and gearing for driving all of the movable parts, except gates and cocks and the lime meter, from a prime motor, thus making the apparatus essentially automatic in operation.

11 is the main driving pulley operated by a suitable prime motor. This pulley drives shaft 12, from which is driven crusher X, and through short shaft 13 drives mixer blades 14, and said short shaft 13, through sprocket l5 drives the conveyer O. Shaft 12 also drives counter shaft 16. Shaft 16, through gearing shown drives the sand meter .9, slaker and agitator shaft 17, and through cross belt 18 drives feed regulator V. It also drives shaft 19. Shaft 19 drives the lime and sand elevators, and through belt 20 drives crank shaft 21, the cranks of which shake the screens, and through cross belt 22 drives the hair picker.

Thelime meter is operated by hand through crank 23 and the water-meteris filled by opening cook 24, and when filled the water is shut off by the same. The sand meter is operated through a mangle gear 25 through which it is rotated about one-half a revolution when it comes to rest for discharging from one cornpartmeut and filling the other. When a second charge is required the operator through lever 26 and its connected pawl moves the meter so that the gears in termesh and the op* eration is repeated.

In operation, the driving pulley being in motion and sand, lime, water and hair being supplied, the lime is first reduced by the crusher X and thence delivered to elevator boot, and lime and sand are simultaneously elevated to the bins or hoppers. The operator now shuts off the water by means of cook 24: and then by crank 23 and cook 8 introduces, in proper pro-determined proportions, a charge of lime and Water to the slaker L where they are agitated and the lime slaked, the lime meter being moved to serve as a gate to close the port leading to slaker. The operator then opens slide gate 27 and the lime paste is discharged through screens h and 11 to mixer M. About the same time the sand meter and the hair picker are brought into operation and lime paste, sand and hair are regularly'fed to the mixer at the same time. When a charge from one set of machinery has been completed and the mortar fully mixed, an operator through lever N and its connections, opens gate G when themortar passes to conveyer G and thence to vats K and while this is in progress the second set of instrumentalities are switched into service and the operation is alternately repeated as long as the apparatus is in operation.
